Newly-promoted Ross County celebrated with a 3-0 win over Dundee at Victoria Park.
The hosts got off to a flying start when Michael Gardyne collected Scott Boyd's pass before finishing neatly inside the area in the ninth minute.
The Dee came close to an equaliser after 23 minutes but Michael Fraser did well to tip Steven Milne's drive round the post.
Iain Vigurs could have doubled the home side's advantage just after the half-hour mark but Robert Douglas produced a fine save to deny him.
Vigurs turned provider just after the hour when he delivered for Colin McMenamin to head home.
Victory was all but ensured three minutes later when Gardyne added his second and the Staggies third with a neat close-range finish.
Both sides were reduced to 10 men in the 80th minute when Kevin McBride and Rocco Quinn were given their marching orders following an altercation.
